mini CORI-FLOW™ Coriolis Mass Flow Controllers

General

The pc-board of a mini CORI-FLOW™ Mass
Flow device features integrated, adaptable PID control for fast and smooth
control of any electronically driven control valve. Depending on the application
this could be an integrated direct acting valve or a separately mounted
valve for special tasks, e.g. a pressure actuated control valve. Integrated
control valves for liquid applications have a purge connection on top of
the sleeve that enables easy elimination of air or gas when starting up
the system. For liquid dosing Bronkhorst offers an alternative way to control
the flow. Instead of using a control valve, the Coriolis flow meter can
be combined with a gear pump, thus eliminating the need of pressurising
the liquid source.

Alternative to Thermal Gas Mass Flow Controllers

Compared to traditional thermal MFCs, Coriolis based flow controllers
offer better accuracy and independence of fluid properties. There are no
moving parts or obstructions in the flow path. Furthermore the Coriolis
sensor is by nature faster than a sensor based on heat transfer. mini
CORI-FLOW™ flow controllers have the same footprint as
typical thermal MFCs for equivalent flow ranges. Also electrically the
instruments feature the same analog (0-5 Vdc / 4-20 mA) and digital (RS232)
outputs as a standard, with optional interface to PROFIBUS DP, DeviceNet™,
Modbus-RTU or FLOW-BUS.

As per the Mass Flow Meter, the enclosure of the Mass Flow Controller
is rugged, weatherproof (IP65). The PN100 rated control valves are available
in normally closed (nc) and normally opened (no) configuration.
